The suspected shooter, Elliot Rodger, posted a YouTube video a day before killing seven, including himself, and wounding dozens, saying he felt rejected by women and would “slaughter” UC Santa Barbara sorority girls.

“If I can’t have you girls I will destroy you,” Rodger said in the video. “You denied me a happy life and, in turn, I will deny all of you life.”

Many began to use the #YesAllWomen hashtag in connection with Rodger to discuss misogynistic behavior and male entitlement towards women in society. Many women shared their own experiences with the hashtag.
